It’s virtually impossible to tease EDUN apart from its rock-star provenance. Such is the star power of U2 frontman Bono, who founded the socially conscious label with his wife, Ali Hewson, in 2005. And indeed, the mood at its Fall/Winter 2013 presentation—an “exploration of youth culture,” according to show notes—at New York Fashion Week on Thursday was equally charged. Models, both male and female, paced frenetically on the circular runway wearing black leather, black skinny jeans, black lamé, and a studied insouciance.
